To @ZZ 'whom t may concern l Be it known that I, GUsTAr AOARLSON,

a citizen of the United States, residing at Chicago, in the county of kCook and State of 5 Illinois, have invented new and useful Improvements in Embroidery Hoops, of which the following'is a specification.

This invention relates particularly to embroidery hoops whereir` an adjustable outer hoop is employed in Vcombination with an inner hoop, `whereby the outer hoop may be clamped upon the inner hoop with the niaterial to be embroidered stretched over the inner hoop and` clamped between' the two hoops.

The primary object is to provide an improved and simplified device of this character which can be cheaply manufactured. which is durable, and which is thoroughly adapted to its purpose.

The invention is illustratedin the accompanying drawing, inv which` l Fig. 1 represents a plan view of theimlproved device; 2, an elevational view of the outer hoop; Figi. 3, fragmentary views of the end portions of the outer hoop; Fig. 4, a detailed Vsectional View taken as indicated at linee of Fig.- l; Fig. 5, a section taken as indicated at line 5 of F k3; and Fig. 6, a section taken at line 6 of Fig. 3,` but Showing the cani device secured in oper-` ative position. n

In the illustration given, A. represents an inner hoop, which may be an endless Vwooden hoop; andB, an adjustable outer hoop constructed in accordance with the invention. y v l The hoop B is preferably formedy of tin plate, or other sheet metal. A strip of suitable sheet metal, or other sheet material, has its edges curled outwardly and then towards each other, the strip being also curved into circular form. Thus the circular strip is provided at its edges with hollow beads 1.` One end of the annular strip has secured within the .hollow beads l comparativelyA stiff wire members 2. These wirevmembf; s project from the end of the metal strip nd are curved to correspond with the curi/a ire of the ring. If desired, the wires may .be secured within the sockets by spot-welding, as at 3, or any other suitable means of securing the wires within their socketsmay be adopted. The projecting ends of the wires are of the other extremity of the annular strip. One end of the strip is equipped with a short metal bar 4, which is disposed between the beads l and secured to the strip, as by spotovelding Lie points 5. One end of the strip 4.- i' ,vided with an outturned cam-stud 4f* lich is disposed substantially flush vwith the end of the strip.

The other end of the strip or annulus is equipped with a short metal bar 6, which is disposed between the hollow `beads l and preferably secured by spot-welding, as at T. The strip 6 is equipped at one end with a pivot-stud 6a, which is substantially flush with the end of the metal strip which forms the annulus. Y Upon the pivot-stud 6a is secured a metal disk 8 which is adapted to rotate freely y on the pivot-stud 6a.

is provided with a cam slot 8@v with which the cam-stud 4a is in permanentengagement, The parts .may be assembled by entering the wire projections 2 in the hollow. beads which form guides therefor, bringing the ends of the annulus approximately together', apply` ing the cari-disk 8 to the stud 6a and rivet- Ving it in position, care being taken to have the cani-stud 4a entered in the cani-slot 8a. The periphery of the cam-disk 8 may be suitably nurled to enable the disk to be turned readily.

Itis Obvious that the construction described enables the ring B to befcont-racted ple, cheap and thoroughly adapted to its purpose.

The yforegoing detailed description has been given for clearness-of understan'ding and no unnecessary limitations should be understood therefrom. v n

What I regard as new and desire to secure by Letters Patent, is:

1. A device of the character set forth comprising a split ringhaving its meeting ends provided with hollow beads, wires secured ing into the guides afforded b v the beads at the other end, a pivot-stud secured to said ring between the beads at one end, a cam-stud secured to said ring between the beads at the other end, and a disk journaled on said pivot-stud and provided with a canislot engaging said cam-stud.

adapted to slide freely in the hollow beads 1 The disk S is a substantial metal disk whichv upon the ring A. The construction issim-y -within said beads at one end and extend-Y ico 2. A device of the character set forth comprising a ring-'form Sheet metal membei` provided with lateral hollow beads, curved Wire members secured Within said beads at one end of the device and workingin the guide afforded by the beads at the other end of the device, a bar secured to said iirst named member between Said beads at one end of the device and equipped with a pivot-stud, a bar secured to Said i'st named member bc- IU tween the beads at the other end of the device and equipped with a cem-stud, and :i cam-disk joui'uaied on said pivot-Stud and having a. cam-Slot engaging said cem-stud- GUSTAF A.
